Endo F is an extremely withered Endoskeleton. Endo F is completely covered in wires, especially in the right side of its face and his torso. Its thighs are also covered by the wires. Its right eye is missing, and its left eye is similar to the other fallen's eyes, but red in color. Endo F's arms are completely gone, in a fashion similar to Withered Chica (Five nights at Freddy's 2), with wires pouring out.

Endo F appears in puzzle 4 of The Basement, where the player must walk down a long hallway and is told to not look back. Looking back or stopping will cause Endo F to attack the player, causing an immediate game over.

Endo F later appears in The Attic, where he will approach from the left entrance. If the player hears footsteps coming from the left, they must shut the left door to prevent Endo F from getting inside.
